Using described_class

If the first argument to an example group is a class, the class is exposed to each example in that example group via the described_class() method.

Access the described class from the example

Given a file named “spec/example_spec.rb” with:

RSpec.describe Symbol do
  it "is available as described_class" do
    expect(described_class).to eq(Symbol)
  end

  describe 'inner' do
    describe String do
      it "is available as described_class" do
        expect(described_class).to eq(String)
      end
    end
  end
end

When I run rspec spec/example_spec.rb

Then the example should pass.
